Preparation Before Operation

Tips for saving energy

Be careful not to cool (heat) the room too much.

Keeping the temperature setting at a moderate level helps save energy.

Cover windows with a blind or a curtain.

Blocking sunlight and air from outdoors increases the cooling (heating) effect.

Operation range

If the temperature or the humidity is beyond the following conditions, safety devices 
may work and the air conditioner may not operate, or sometimes, water may drop from the indoor unit.

DB: Dry bulb temperature  WB: Wet bulb temperature
The setting temperature range of the remote controller is 16°C to 32°C.

Useful Information

Observe the following precautions to ensure the system operates properly.

Set the room temperature appropriately.

Take care not to cool or heat the room excessively.

Adjust the temperature so that everyone in the room is comfortable.

Ventilate the room from time to time.

Be sure to ventilate the room after using the air conditioner for a long time.

Do not leave the door or window open.

The air will be released, and the effect of cooling/heating 

will be reduced.

Do not allow direct sunshine to enter the room 

during the cooling operation.

Hang a curtain or blind to the window to prevent direct sunshine.

Keep televisions, radios or stereo equipment at least 

1 meter from the indoor unit or remote controller.

Otherwise, picture 

disturbance or 

noise may result.

Use flow direction adjustment skillfully.

Cold air collects toward the floor and hot air collects toward 

the ceiling. Therefore, for cooling, set the air flow horizontally,

 and for heating, set the air flow downward. Also, set 

the air flow so that it does not blow directly on your body.

26-28˚C

during

cooling

20-24˚C

during

heating

Turn off the power when the air conditioner is not 

used for a long time.

With the power on, the air conditioner will consume 

several to several tends of watts of power (

1)

NOTE

1The power consumption while the equipment is stopped 

varies with the type of outdoor unit, etc. Consult your 

dealer for further details on power consumption.

Do not use and room heater under the indoor unit.

Heat may deform the indoor unit of suction grille.

Do not place things near the air outlet or air inlet.

Such obstacles may lower the performance of the air 

conditioner or make it stop.

When the display shows “

 ” (TIME TO CLEAN 

AIR FILTER), refer to the instruction manual of the 

indoor unit, and clean the air filter.

Use timer operation effectively.

It takes time for the room temperature to 

reach the set temperature. Therefore, use 

timer operation to start the air conditioner 

ahead of time.
